The Shapecfg program configures and adjusts traffic shaper
bandwidth limiters. Traffic shaping means setting parameters
to which traffic should conform - setting the standards for
bandwidth consumption.
To use Shapecfg, you must have also installed the kernel which
supports the shaper module (kernel versions 2.0.36 or later and
late 2.1.x kernels).
Install the shapecfg package if you want to set traffic
bandwidth parameters, and if you have the appropriate
kernel.
